  • Whilst CuO possesses spontaneous electrical polarization induced by its magnetic order, no magnetoelectric control of one by the other has been observed. Here, the authors demonstrate modification of the electrical polarization of CuO by suppressing its magnetic helix via an applied magnetic field.

  • Determining the spatial dynamics of excited carriers will provide a more complete understanding of ultrafast carrier dynamics in materials. Using scanning ultrafast electron microscopy, Najafiet al. are able to observe the spatiotemporal dynamics of excited electron and hole carriers in silicon.

  • Defect engineering and doping of semiconductors by ion irradiation are essential in large-scale integration of electronic devices. Here, intense ion pulses from a laser-accelerator, with flux levels up to 1022 ions cm-2 s-1, are used to induce and optimize silicon color centers and photon emitters in the telecom band.
